This document describes how the Siebel Connector handles Siebel LOV (List Of Values)

Solution:

LOV are read-only within IM and used to assign to other object types, such as user accounts. Only the LOV field types that are used in mappings will be explored.

For example, you can map the Siebel field 'Employee Type Code' using the Combo Box Control Type and specify EMPLOYEE_TYPE as the Siebel LOV type. A re-exploration of the endpoint will add all EMPLOYEE_TYPE values to the List Of Values container, and user accounts will have this mapped field in the Profile tab populated with their employee type. This mapped field can also be edited, with all possible values available to pick from the combo box.
